That might be nothing more than the

From:

line in the e-mail.  Does the actual received address show:

root@<hostname>.hamcoll.sa.edu.au <root at hamcoll.sa.edu.au>

or

root@<hostname>.hamcoll.sa.edu.au <root@<hostname>.hamcoll.sa.edu.au>

If it's the first, then your fine, it is because the periodic
script is generating the From: line in the body of the e-mail
message.

Some masquerading option must be set on it.  Once again, check the
received message to see if the real senders envelope address is getting
munged, not
just the From: address.
